Abstract
The utility model discloses a bed sheet replacing device which comprises a bed body, a bed plate, a driving shaft, a driven shaft and a motor. The driving shaft and the driven shaft are used for winding a bed sheet, and the motor is used for driving the driving shaft to rotate. The bed plate is fixed on the bed body and used for the bed sheet to place in a paved mode, and the driving shaft and the driven shaft are arranged at the head end and the tail end of the bed body respectively. The driving shaft and the motor are coaxial for direct driving without a switch-over structure. The technical problem that the driving shaft is twisted or even broken due to uneven force bearing is solved. When the bed sheet is replaced, the motor is started to drive the driving shaft to rotate, the used bed sheet is pulled out of the bed plate and wound on the driving shaft, then the driven shaft is driven to rotate to pull out a bed sheet used for replacing wound on the driven shaft, the bed sheet to be replaced is arranged on the bed plate in a paved mode, and bed sheet replacement is achieved.
Description
Technical field
This utility model relates to a kind of medical auxiliary facilities, is applicable to the environment for use frequently more changed the sheet, and refers to especially a kind of bed sheet changing device that can automatically more change the sheet.
Background technology
Because patient's mobility is larger, in order to guarantee safety and sanitation, reduce viral pollution spread, the specific inspection of some of hospital place (as CT scan bed, B ultrasonic bed) etc., need more to change the sheet frequently, realizes that a people one is single.At some,, also there are such needs in place as large as flows of personnel such as beauty parlors, other place.The work more changed the sheet at present is most of for changing list manually and common electric is changed list.Manually change single workload large, increase medical worker's work load.Common electronic rotation of changing single employing Electric Machine Control driving shaft, pull sheet to be wound on driving shaft, drives driven shaft and rotate, and the sheet be wrapped on driven shaft is pulled on bed board, realizes from moving list.But, existing common electric is changed single motor and is driven the driving shaft rotation by changeover mechanism, along with the sheet thickness be wound around on driving shaft constantly increases, when the driven by motor driving shaft rotates, the stressed of driving shaft can strengthen, and because changeover mechanism connects motor and driving shaft, causes driving shaft each several part unbalance stress, very easily cause even off-axis of distortion, greatly have influence on the service life of driving shaft.
The utility model content
In view of this, the purpose of this utility model is to propose a kind of bed sheet changing device, uses nonwoven fabric roll shaft type sheet as consumptive material, adopts variable-frequency direct-drive to control, and solves driving shaft unbalance stress that the variation because of sheet weight causes, the easy problem of off-axis.Adopt the specific speed checkout gear simultaneously, detect the sheet translational speed, frequency control, guarantee sheet translational speed uniformity.
A kind of bed sheet changing device provided based on above-mentioned purpose this utility model, comprise a body, bed board, for driving shaft and driven shaft and the motor for driving driving shaft to rotate that is wound around sheet, wherein said bed board is fixed on a body, for elaborating sheet, described driving shaft and driven shaft are arranged on respectively the two ends end to end of described bed body, described driving shaft and described motor coaxle directly drive, without exchanging structure, starting the described driving shaft of described driven by motor rotates, to pull out bed board and be wrapped on driving shaft with the sheet of crossing, and then drive described driven shaft and rotate, change the sheet and pull out being wrapped in treating on described driven shaft, elaborate on described bed board.Due to driving shaft and motor coaxle, in the time of can guaranteeing that the driven by motor driving shaft rotates, driving shaft each several part mean forced.
Described is permagnetic synchronous motor for driving the motor that driving shaft rotates, and adopts closed-loop vector to control, can assurance speed switching nature steady.
Between described bed board and described driving shaft, the axis of guide is installed, described driving shaft rotates and pulls out sheet, and sheet is wound on described driving shaft after the described axis of guide.
On the described axis of guide, be equipped with for feeding back the counting assembly of the sheet speed of service.
Described bed sheet changing device also comprises for controlling the converter of described motor speed, and during the sheet progressive additive that is wound around on driving shaft, the rotating speed of motor can slow down, and it is steady that converter can be controlled the rotating speed of motor, guarantees that bed sheet replacing speed is unaffected.
As can be seen from above, the bed sheet changing device that this utility model provides can solve that manually to change single workload large, and common electric is changed single problem of easily damaging driving shaft.
The accompanying drawing explanation
Fig. 1 is this sheet changer embodiment schematic diagram;
The coaxial connected mode schematic diagram that Fig. 2 is driving shaft and motor.
The corresponding relation of the Reference numeral in figure and its parts that refer to is:
1, the bed body; 2, bed board; 3, sheet; 4, driving shaft; 5, driven shaft; 6, the axis of guide; 7, motor.
The specific embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with specific embodiment, and, with reference to accompanying drawing, this utility model is further described.
Bed sheet changing device as shown in Figure 1, bed board 2 is fixed on a body 1, for elaborating sheet 3, driving shaft 4 and driven shaft 5 are arranged on respectively the two ends end to end of a body 1, one of sheet 3 is being wound around on driving shaft 4, and driving shaft 4 rotates and the sheet 3 with crossing can be pulled out to bed board 2, is rolled onto on axle; Be wound with stand-by sheet on driven shaft 5.The rotation of driving shaft 4 is driven by motor 7, and starter motor 7 drives driving shafts 4 and rotates, and will pull out bed board and be wrapped on driving shaft 4 with the sheet of crossing, and then drive driven shaft 5 and rotate, and by being wrapped in treating on driven shaft 5, changing the sheet and pulls out, and elaborates on bed board 2.
As shown in Figure 2, motor 7 and driving shaft 4 coaxially directly drive, without exchanging structure.Along with the sheet of the winding on driving shaft 4 is thickeied gradually, driving shaft 4 rotates and stressedly also continues to increase, and Driven by Coaxial guarantees that driving shaft 4 each several parts are stressed evenly.
Optionally, be arranged on an end of described driving shaft 4 for the motor 7 that drives driving shaft 4 to rotate, realize Driven by Coaxial.
Optionally, for the motor 7 that drives driving shaft 4 to rotate, be permagnetic synchronous motor, the switching of closed-loop vector control assurance speed is naturally steady.
Optionally, as shown in Figure 2, between bed board 2 and driving shaft 4, the axis of guide 6 is installed, driving shaft 4 rotates pulls out sheet, and sheet is wound on driving shaft 4 after the axis of guide 6.
Optionally, be equipped with on the axis of guide 6 for feeding back the counting assembly of the sheet speed of service, be convenient to monitoring and regulate.
Optionally, also comprise for controlling the converter of motor 7 rotating speeds.Along with the increase of the sheet thickness be wound around on driving shaft 4, the rotating speed of motor 7 can slow down gradually, and in order to keep the each scrolling speed of changing of sheet consistent, can regulate by converter the rotating speed of motor 7.
